title: Chloridobis[2-(diphenylphosphanyl)ethanamine-κ(2)P,N](triphenylphosphane-κP)ruthenium(II) chloride toluene monosolvate.
abstract: The aminophosphane ligand 1-amino-2-(diphenylphosphanyl)ethane [Ph2P(CH2)2NH2] reacts with dichloridotris(triphenylphosphane)ruthenium(II), [RuCl2(PPh3)3], to form chloridobis[2-(diphenylphosphanyl)ethanamine-κ(2)P,N](triphenylphosphane-κP)ruthenium(II) chloride toluene monosolvate, [RuCl(C18H15P)(C14H16NP)2]Cl·C7H8 or [RuCl(PPh3){Ph2P(CH2)2NH2}2]Cl·C7H8. The asymmetric unit of the monoclinic unit cell contains two molecules of the Ru(II) cation, two chloride anions and two toluene molecules. The Ru(II) cation is octahedrally coordinated by two chelating Ph2P(CH2)2NH2 ligands, a triphenylphosphane (PPh3) ligand and a chloride ligand. The three P atoms are meridionally coordinated, with the Ph2P- groups from the ligands being trans. The two -NH2 groups are cis, as are the chloride and PPh3 ligands. This chiral stereochemistry of the [RuCl(PPh3){Ph2P(CH2)2NH2}2](+) cation is unique in ruthenium-aminophosphane chemistry.
